I think you just need to find yourself a nice groove and work with it... :)
Though, writing the word 'trees' for vegetation might be a little bad; even if you think it sucks, you should really try to treat each panel like your most important work!
OR you can do what many people do (like me!) and use pictures in place of drawing backgrounds. This is probably not the best way of doing things, and I have been working on getting out of the habit, but you can do it, if you're a beginner or really really don't want to draw it. XD
